Completion of the Custom Wiring Harness Worksheet
The second page of this document is the wire harness worksheet that must be completed, printed
and FAXed or emailed back to PS Engineering, Inc. Upon the receipt of the worksheet, PS
Engineering, Inc. will debit the credit card for the entire amount of the harness plus any other
additional hardware or shipping charges that are indicated on the wire harness worksheet.
Wire Harnesses are not cancelable or returnable.
Allow five-business days from our receipt of your harness worksheet to the time the harness is
shipped.
The best technique to measure the needed cable lengths is to take a piece of string, and run it from
the desired unit location to the desired jack location, next to, or through the aircraft structure
along the planned cable route. Then measure that string to determine the wire run. Repeat for
each individual run (pilot jacks, passenger jacks, music jacks etc.).
Enter the length in the “Length (feet)” column. If any of the column boxes are empty, then PS
Engineering will assume that wire connection is not required or needed.
Ordering a harness with excessive wire lengths will increase the likelihood of Radio Frequency
Interference (RFI). The only alternative to a too long a wire run is to cut it to length. However,
this eliminates the work that had already been done in prepping the wires and will require special
tools to re-prepare the wires for termination to the mic and headphone jacks.
In order to use the Push-to-Talk intercom function of the PM1200, you must connect two
normally-open, single pole momentary switches (switches not included) as shown in the
installation manual. These wires are labeled PPT and CPT on the order sheet, and should be
located conveniently to the pilot and copilot position, such as on the throttle.
We typically do not install intercom headphone jacks on the harness unless specifically requested
by adding the quantity of jack sets (headphone and microphone). It is usually easier to feed the
wires through the airplane without the jacks attached to the harness. However, if you elect to have
us install jacks to your harness we will be glad to do so. Since the PM1200 comes with a set of
jacks, you will wind up with an extra set. (These “extra jacks” are non-returnable).
Power and ground wires will be the length you specify. The lengths should include the distance
from the circuit breaker on the avionics bus (power) and the ground location (ground) to the
PM1200.
The radio interface is accomplished at the “Auxiliary” Microphone and Headphone Jacks. See the
Installation Manual for details as well as our Frequently Asked Questions (FAQ) on our website.
The additional jacks, which must be labeled "Auxiliary Mic; Auxiliary Headphone," serve several
purposes. They allow a systematic method of installation. These jacks can be used as a
troubleshooting tool as well as your only way to connect to your radios if you remove the
intercom for any reason.
